PROVIDENCE, R.I. >> A Rhode Island man has been convicted of threatening to kill an Internal Revenue Service agent and rape and kill the agent’s wife over a $330,000 tax bill.

A federal judge on Friday found Cranston resident Andrew A. Calcione guilty of threatening to assault and murder an IRS revenue agent and his family.

Prosecutors say Calcione left voice mail messages in the Warwick IRS office on July 15 threatening that if the agent called him again, he would torture the agent, rape and kill his wife and injure his daughter while the agent watched. He said he would then kill the agent.

Tax agents estimated that Calcione owed $330,000 for 2008, 2009 and 2010.

The 49-year-old Calcione faces up to 20 years in prison when he’s sentenced Sept. 11.
